... it bumps into. Momentum depends on mass and velocity. You can calculate momentum by using this formula. momentum = mass x velocity In the example, the truck has a far greater mass than the car. So the momentum of the truck is much greater than the momentum of the car. The truck will be harder to sto ...

Hunting oscillation
Hunting oscillation is a self-oscillation, usually unwanted, about an equilibrium. The expression came into use in the 19th century and describes how a system ""hunts"" for equilibrium. The expression is used to describe phenomena in such diverse fields as electronics, aviation, biology, and railway engineering.
